RADIATOR.

Specification of Letters Patent.

Patented Apr. 27, 1915.

Application filed March 20, 1914. Serial No. 826,010.

To all whom it may concern:

Be it known that I, Josnr a A. KonNz, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Radiator; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Wlll enable others skilled in the art to which it appertains to use and make the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to devices for cooling water heated by internal combustion ennes. The invention is particularly applicable to automobile radiators for reducing the temperature'of the water which passes through the cooling jackets of the automobile engines. The object of the invention is to provide efficient radiators which may be cheaply constructed, easily made and mounted and yet which are durable and of long life.

By my invention radiators are provided which produce rapid cooling of the water and also a rapid movement of the water through the radiator and jacket of the enne. By my invention the walls of the cells are so shaped that as portions of the water pass by the cells, the water first has opportunity to acquire some velocity as it has free fall for a short distance and then it is turned and dashed or directed upward to a sharp corner in the wall of the cell bringing the water into close contact with the walls of the cell. It then again falls downward acquiring anew some velocity added to the velocity that may be caused by the reaction of the impact produced by the sudden change of the direction of the movement of the water. wall of the cell and directed into a sharp corner formed by the walls of the next lower cell. The walls of the'cell may be first curved outward and then inward forming heart shaped cells.

It is again turned upward by the The invention may be contained in many constructions all of which come within the purview of my claims hereinafter appended. To show the practicability of constructions embodying my invention, I have selected one of such constructions as an example and shall describe it hereinafter. The construction selected is illustrated in the accompanying drawings.

Figure 1 of the drawing illustrates a front view of a radiator containing my invention. Fig. 2 illustrates a perspective view of a part of the radiator that is, a cluster of cells used in the radiator shown in Fig. 1. Fig. 3 illustrates a section of the parallel walls. Fig. 4 illustrates a modification of the invention in which the walls are provided with end flanges which abut each other. Fig. 5 shows a section of the walls of one of the cells shown in Fig; 4:

Referring to the drawings, 1, Fig. 1,is the radiator frame of the usual construction and is provided with a chamber in its upper end 2 and a chamber in the lower end 3. Communication is established from one chamber to the other chamber through the walls surand 13 are provided with over-lapping turned edges 14 and 15 which space the walls '11 and 13 and the walls 10 and 12. The walls of the cells may be placed in position and then the cells may be dipped in solder about one-eighth of an inch so as to solder the cell walls together at the ends of the cells. The solder will thus fill the ends of the cells 16 as at 17, at the same time the solder solidifies between the sides of the cells as at 18, securing the cells together.

If desired, the walls 10, 11, 12 and 13, may be provided with off-sets 20 formed by a double right angled turn of the edges forming inwardly turned portions 21 and outwardly extending portions or flanges 22, as shown in Figs. 4 and 5. In assembling the radiator to form the cells, the walls 10 and 12 and the walls 11 and 13 are placed so that the sides of the flanges 23 located at the ends of the cells abut each other whereupon the radiator cells may be dipped in solder and the ends of the chambers formed between the walls 10 and 12 and the Walls 11 and 13 will be sealed by the solder 24: which enters and solidifies at the ends of the chambers at the ends of the walls. The cells are also secured together at the same time by the dip in the solder.

The water passes to the upper row of the cells from the upper end 2 of the radiator. It passes down the opposite sides of the inverted heart shaped cells between the walls falling at first nearly perpendicular. By this means the water acquires some velocity and it is then directed around to an upper direction. This causes the water to some extent, to be rapidly directed into the sharp corners 25 and brings the water with some impact against the inner walls 10 and-11 at the apices of the hearts as at 26.

In order that the water may have a substantially perpendicular fall through the height of the radiator and have substantially a free fall as it passes each cell for a short distance and then subsequently turned upward, the walls of the cells are first curved inwardly, the center of curvature being located on the outside of the cell and then they are curved outward on a curve having a short curvature, the center of curvature being located preferably within the cell. This gives substantially a semiheart shape to the walls of the cell which, when placed together, form heart shaped cells. The direction of the walls at the apicesof the heart approach the perpendicular and then curve inwardly on a comparatively long curve which gives considerable velocity to the water. The walls then curve outwardly bringing the water with a sharp turn upwardly toward the center of the cell.

The water is rapidly cooled by reason of the fact that when flowing over the curved walls its direction is being constantly changed and consequently it is kept in close contact bythe centrifugal action due to the curvature of the walls. This is particularly true when the water is permitted to acquire some velocity. The stopping of the movement of the water by the sudden change of direction produced at the end of the short curve in the lower part of each heart shaped cell brings the water in excecdingly close contact with the cooling surface of the metal at that point and further aids in the cooling process.

The water first starts downward nearly perpendicularly on a comparatively long curve. It is then turned inward on a sharp curve and brought to a sudden stop. The

water again starts downward past the next row of cells falling nearly vertically for a short distance, whereupon it is again brought to nearly an upward direction by sharp curves around the heart shape cells. The water, thus as it passes each row of cells, is affected by the sharp curves and angles of the walls forming the chambers in which it is contained and is rapidly cooled thereby.

The shape of the walls is also such that no sediment may collect at the lowest level of the heart shaped chamber in which the water passes by reason of the factthat the water has substantially a free fall for a short distance before it reaches the points at which sediment might collect. The water washes through the low level of the cham-- bers about the cells and.washes any sedi-.

'ment out that might collect therein. By reason of the curvature of the chambers at these points, the water will tend, not only by reason of gravity, to wash the outer wall of the chamber, but also by reason of the fact that the shape of the chambers at these points causes a constant change in direction of the water producing thereby a centrifugal force which washes the outer walls of the chambers and consequently any sediment that might collect at the bottom point of curvature of the chambers is carried away. g

The construction selected and described may be greatly varied in the arrangement and construction of its parts and in the substitution of the elements having equivalent functionsv and such modifications may still contain the invention.

WVhat I claim as new and desire to secure by Letters Patent is as follows:

1. A radiator having inverted heart shaped cells surrounded by two pairs of substantially parallel walls forming water passageways having semi-heart-shaped contours, the water entering the apices of the heart-shaped cells and passing around the opposite sides of the heart-shaped cells.

2. A radiator having cells separated by pairs of substantially parallel walls forming water chambers and, from point to point, extend downward a short distance and then extend upward, the downwardly extending portions extending to the top of the upwardly extending portions andforming abutting surfaces and a sharp corner at the termination of the upwardly extending portions and at the beginning of the downwardly extending portions.

3. A radiator having heart-shaped cells separated by a pair of substantially parallel walls forming narrow water passageways extending vertically through the radiator, the walls surrounding the cells being inclined on an outer curve downward for a short distance then turning inwardly and upwardly on a short inner curve of small curvature signed my name to this specification in the and then starting vertlcally downward and presence of two subscribing wltnesses. inclined to an outer curve downward for a short distance and then turning inwardly JOSEPH A.
